engage the shackle when the same is unlocked to hold the bolt in unlocked position.

of shell 28 is opposite the opening 32, whereupon the locking mechanism may be moved downwardly into the position shown by Fig. 5 of the drawing. The bolt is then assembled .on the upper face .of roll-back 33 in the position shown in Fig. 5, whereupon the locking mechanism, together with the bolt, may be moved upwardly to bring stud 21 into -openingfl22. ".Theshackle is then forced inwardly into the casing 11 and the locking mechanism and bolt rotated into the position shown in Fig. 1 of the drawing,

whereupon the plates 39 and i0 may be assembled on the sides of the casing '11. The plates 39 and/i0 may be secured to casing 11 in any preferred manner, in the present instance theedges of the plates being chamfered as shown in Figs. 3 and 4, and the edge portions of the casing 11 bent around the chamfered edges of the plates to hold the latter against detachment from the casing. Alternately the parts of the lock may be assembled by first assembling the bolt member 20 within the lock case in its operative position as shown in Fig. 2. The lock mechanism 27 may then be tipped slightly and the-end of the key barrel 31 inserted in the opening'32, after which the body of the lock mechanism may be moved to the position shown in Fig. 5 about the keybarrel as a pivot, thenby raising the shell 28 so as to clear the shoulder 49, the lock mechanism may be rotated to operative position as shown in Fig. 1.

The Shell 281s of such thickness that a contacts with plates 39 and 40, as shown in Fig.3 of the drawing, andis provided with ribs 46 and 46? adjacent to lug 35, ribs 46 anddti engaging theinnerfaces of plates 39 and to assist inholding the locking mech anism against movement within the casing.

The ends 23 and 240i dog 20, are provided with semi-circularportions 437 and 48, which .While I have shown and described a preferred embodiment of my invention, it will be understood that itis not to be limited to V the details shown, but is capable of modification and variation within the spirit of the invention and scope of the appended claims.

What I claim is: 1. In a padlock, a casing having an opening therein, a key operated mechanism and a bolt posite faces, a bolt pivotally seated' on one" of the faces of said opening and presenting a relatively flat face towards the opposite face of -the opening, a key operated mechanism mounted in and fitting the space between the fiat face of the bolt and the opposite face of the opening to hold the bolt against movement away from itsseat, and said casing being provided with a recess into which the.

key operated mechanism may be moved in a direction away from said bolt to freethe latter for movement away from its seat and outof the lock casing.

' 4. In a padlock, a casing having a general-j ly transversely directed opening therein provided with opposite faces, a bolt pivotally seated on one of the faces of said opening and presenting a relatively flat face towards the opposite face of the opening, a key operated mechanism mounted in and fitting the space between the flat face of the bolt and the opposite face of the opening to hold the bolt against movement away from its seat, and said casing being provided with a recess into which the key operated mechanism maybe moved uponrotation thereof, the key operated mechanism being moved into said recess in a direction away] from said bolt to free the latter for movement away from its seat.

5. In a padlock, a casing having a generally transversely directed opening therein provided with oppositefaces, a bolt, anda key operated mechanism for said bolt mounted between the opposite faces of the opening and mutually supporting one another in the casing, said casing being provided with a recess into which one of said mutually supporting devices may be moved to free the other there of for'movement into and out of said casing.

6. In a padlock, a casing having a generally transversely directed opening therein provided with opposite faces, a bolt, and'a If key operated mechanism for said bolt mountedbetween the opposite faces of the opening and mutually supporting one another in the casing, said casing being provided with a recess into which one of said mutually s'up- TL porting devices may be moved upon rotation thereof to free the other thereof for movement into and out of said casing.

7 In a padlock, a casing having a transversely directed opening therein provided with'opposite faces each of which is intersected by a recess, a bolt seated on one of said faces and having a stud in the recess therein,

a key operated 'mecha-nism seated between 7 said bolt and the opposite face and having a stem extending into the recess in the opposite face, and said casing being provided with a third recess into which one of these devices may be moved to free the other for movement out of the lockcasing.

8. In a, padlock, a casing, a shackle mounted on said casing, and means for locking said shackle against movement with respect to said casing, said casing being provided with an opening having opposite faces, each of which is provided with a cylindrical recess opening therein, said locking means for said shackle comprising a bolt seated against one of said faces and having a stud extending into the recess opening thereinto,'and a key operated mechanism mounted in vand fitting the space between the bolt and the other of said faces, said mechanism having a stem extending into the recess opening into the last named face, and said casing being provided with a third recess into which one of said devices may be moved to free the other thereof for movement into and out of the lock casing.

In witness whereof, I have hereunto set my hand this 17 day of June, 1930.
